Homework Answers
All are correct except Q.20 which will be B
12. E is correct. Ketone is the most oxidised compound followed by alcohol and hydrocarbns are the least oxidised compounds. Hence E option is correct.
15. B correct, because H2/Pd being a strong reducing agent reduces both double bond and -C=O group. LiAlH4 and BaBH4 being a mild reducing agent reduces only -C=O group.
19.D is correct. In all of the above cases same product 2-methyl-1-phenyl-2-butanol
20. B will be correct. This can be explained on the basis of the following reaction reaction mechanism.
